摘要
Abstract
This paper deduced a pressure drop calculation model based on the analysis of the percolation mechanism and the principle of conservation of mass and momentum theorem. It also introduced a modified skin friction coefficient to calculate accurately the pressure drop of each infinitesimal section after partition. In addition, it deduced the three-dimensional steady-state seepage potential distribution and stress distribution formula according to the type of the bottom-water drive reservoir and the potential of superposition principle and mirror image principle. Then it established the three-dimensional steady-state hydromechan-ical coupling productivity prediction model. The actual calculation of the horizontal wells after the partially completion proves that this model can be more precise in calculating the production capability. The distribution of the flux and pressure along the well in the constant rate production can be obtained by iterative solution. The model provides a basis for partially completion and horizontal well length optimization.关键词
